RISH Ducer M01 is a programmable transducer with RS 485 bus interface (MODBUS®) It supervises several parameter of an electrical power system simultaneously.
The RS 485 interface enables the user to determine the number variables to be supervised (up to the maximum available). The levels of all internal counters that have been configured (max. 4) can also viewed. Provision is made for programming the RISH Ducer M01 via the bus. A standard EIA 485 interface can be used.
The transducers are also equipped with an RS 232 serial interface to which a PC with the corresponding software can be connected for programming or accessing and executing useful ancillary functions.
This interface is needed for bus operation to configure the device address, the Baud rate and possibly increasing the message waiting time (if the master is too slow) defined in the MODBUS® protocol.
The usual methods of connection, the types of measured variables, their ratings and the type of internal energy/metering are the main parameters that can be programmed.
The ancillary functions include a power system check and a facility for printing nameplates.
The transducer fulfils all the essential requirements and regulations concerning electromagnetic compatibility (EMC) and safety (IEC 1010 resp. EN 61 010). It was developed and is manufactured and tested in strict accordance with the quality assurance standard ISO 9001.
